Description

technical field [0001] The invention relates to an onium compound and a preparation method thereof, in particular to 5,10,15,20-tetrakis(N-hydrocarbyl-4-pyridinium)porphyrin lead iodate and a preparation method thereof. Background technique [0002] Nitrogen-containing onium salt compounds have high research and application value in many fields such as chemistry, biology, and medicine, and are important materials in phase transfer catalysis, organic synthesis, photosensitivity, and optoelectronics. [0003] Most of the nitrogen-containing onium salt compounds reported in the literature are mainly monovalent, among which a wide variety of alkylammonium onium salts and nitrogen-containing heterocyclic onium salts are represented. The synthesis of monovalent ammonium salt is relatively easy, and the product is relatively stable, and can participate in a variety of efficient ring-forming reactions, rearrangement reactions, etc., and is an ivy in the field of organic synthesis. ...

AI Technical Summary

Problems solved by technology

[0005] Among many nitrogen-containing heterocyclic substrates, porphyrin and its derivatives are widely used in many research fields. However, through chemical modification, four pyridyl groups are added to the 5, 10, 15, and 20 positions of the porphyrin ring to form 5, 10,15,20-Tetrakis(4-pyridinyl)porphyrins, and further alkylation to form tetrakis(N-alkyl-4-pyridinium)porphyrins with four positive charges are rarely reported, and now Raw materials such as halogenated hydrocarbons are relatively toxic, and the product is an amorphous structure, so it is impossible to study the physical and chemical properties of this type of four (N-alkyl-4-pyridinium) porphyrins, which limits its practical application; in view of this , it is very meaningful to find a method for the synthesis of tetrakis (N-alkyl-4-pyridinium) porphyrin with universality, simple equipment and process, and environmental protection. At the same time, determining its single crystal structure will make it possible to understand the The special physical and chemical properties of this type of compound make this type of compound have a wider range of applications
